Need help with calculated column

Question

I need column1 to determine the value of column2.

So If column1 equals yes column2 needs to equal yes;

and

If column1 equals no then column2 should equal no

Answer 1

You can do it as

=Column1

Since you said if column1 = yes the column2 = yes

If you are looking for more logic.. then the conditional logic goes as

=if(column1="Yes", "Yes", "No")
